Application filed March 13, 1922.

marked thereon, which form a part of this specification.

The primary object of my invention is the provision of a plane of the type used by carpenters, which is simple and inexpensive in its construction, composed of a minimum number of parts, and is easily and quickly operable to adjust and clamp the blade with respect to the stock.

The invention is fully described in the following specification, and while in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Fig. 1 is a top plan view of a plane embodying the invention. Fig. 2 is a side elevation thereof, and Figs. 3 and 4: are cross-sections on the lines 3-3 and H, respectively, in Fig. 2.

Referring to the drawings, 1 designates the stock of a plane embodying the invention, which stock is preferably formed U- shape in cross section from sheet metal and comprises the sole 2 and opposed sides 3. The material from which the stock is formed is preferably of sheet steel to render the sides resilient to a limited extent with respect to the sole 2. r

The blade 4 of the plane is inclined with respect to the sole 2 and has its cutting edge adapted to project through the customary mouth or slot 5 in the stock sole, the blade resting at its rear side adjacent to its forward or cutting edge against the rear bevelled wall of the mouth 5, and resting at a point at the rear of such wall, on a bolt or cross-piece 6, which extends through and connects the two sides 3 of the stock, such bolt being disposed the proper distance above the stock sole to get the desired inclination to the blade. The forward edge Serial No. 543,295.

portion of the blade is held in longitudinal adjustable engagement with the rear wall of the mouth 5 by lugs 7 which engage over the adjacent side edges of the blade as shown. The lugs are shown in the present instance as being pressed from the side walls 3 of the stock. I

The blade 4: is of a width substantially the same as the normal width of the space between the side walls 3 so that the blade is adapted to have a sliding fit between the sides 3 to permit free longitudinal sliding adjustment of the blade with respect to the stock. When the desired adjustment has been obtained the blade is securely clamped in adjusting position by a tightening of the bolt 6, which effects an inward drawing of the resilient sides 3 against the opposed side edges of the blade. Such adjustment of the bolt 6 is facilitated by providing a thumbnut 8 at one end thereof.

It is evident that my plane comprises only three parts, namely, the stock, the bladeand the clamping bolt, thereby enabling it to be manufacturedat very small cost at the same .time rendering it strong and durable in its construction.

I wish it understood that my invention is not limited to any specific construction, arrangement'or form of the parts, as it is capable of embodiment in numerous forms without departing from the spirit of the claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is, i

1. In a plane, a stock having a blade receiving mouth in its soleand resilient side walls rising from the edges of the sole, a clamping bolt connecting the side walls, and a blade disposed between the side walls and resting at its forward edge against the rear edge of the sole mouth and at the rear of the mouth against the clamping bolt, said clamping bolt being operable to relatively contract the sides to grip the opposed side edges of the blade and hold it in adjusted position.

2. A plane comprising a stock U-shape in cross section and having a blade receiving mouth in its sole, the sides of the stock being resilient, a bolt connecting the sides of the stock and adjustable externally of the stock to effect an inward drawing of the sides from normal position a blade inclined With respect to the sole and resting at its forward edge against the rearedge of the sole mouth and at the rear thereof against the top of the bolt, the blade being clamped in adjusted position by an inward drawing of the opposed sides of the stock having projections at their inner sides for engaging over the LAM-8,044

adjacent side edges of the blade near the cutting edge thereof.

In testimony whereof I have hereunto subscribed my name to this specification. EVERETTE L. ULRICH.
